RESUMO
CONTEXT: The International Narcotics Control Board's (INCB) opioids consumption data are often cited in the literature and by policy makers to benchmark the adequacy of pain management among different countries. This practice may be inaccurate as INCB data does not account for variations in disease burden and use of other pain medications and only controls for population sizes differences among countries. OBJECTIVE: To demonstrate that INCB consumption data may not be an accurate/sensitive indicator for pain management adequacy due to significant inter-country variations in disease burden and in the use of pain medications that are not reported by INCB. METHODS: We compared opioid consumption data between 2012 and 2016 for Jordan and King Hussein Cancer Center vs five high-income countries (United States of America, United Kingdom, France, Sweden, and Japan) taking into consideration the cancer burden in those countries. In addition, we examined the significance of tramadol utilization in the setting of cancer pain management. RESULTS: Jordan's INCB-reported opioid consumption is ostensibly low at a median of 291 sDDD/million inhabitants/day. Compared to Jordan, the median consumption in the five HICs is 34 (range 4-172) times that of Jordan. However, when consumption is adjusted to cancer burden data, the gap is significantly reduced to a median of 2 (range 0.2-24) times that of Jordan and in the case of one institution's experience, the gap is eliminated. Furthermore, Jordan's tramadol's median consumption between 2012-2016 of 176 kg is equivalent to 127% of morphine consumption on an equianalgesic basis. CONCLUSION: INCB data should not be utilized to benchmark the adequacy of pain management among different countries without taking into consideration variations in disease burden and the use of tramadol and other pain drugs.
